Portuguese term or phrase: O backbone ótico entre as salas PTA e LTA

The full sentence is as follows:
***O backbone ótico entre as salas PTA e LTA*** e interligação das duas salas PTA suporta até 10GB de velocidade e entre as salas PTA e SC.

I'm struggling with the abbreviations PTA and LTA. Does anyone know what they stand for?
They appear in other parts of the text too, here are some examples:
Das salas técnicas (LTA) o cabeamento horizontal é estruturado...
como as salas técnicas principais de telecomunicações PTAs...

The text is about the security systems and fire fighting systems in a stadium in Brazil. If anyone can help that would be much appreciated.
